This study shows that symbiotic microalgae enhance photosynthetic production and carbon storage within a host, driven by host energetic demands.

The paper investigates the cellular integration and diel remodeling of the nitroplast in Braarudosphaera bigelowii, revealing its structural interactions and dynamic membrane changes.

The paper introduces an Advanced Mobile Laboratory (AML) for field-based microbial ecology and cell biology, enabling multiscale analysis of environmental samples directly at the sampling site.

The paper assesses subcellular carbon storage and chloroplast organization in coral symbionts across light gradients, finding spatial differences in cell volume and starch accumulation.

FeatureForest uses foundation model embeddings with random forests to enable fast, accurate segmentation of complex biological images with minimal labeling.

The paper discovers host actin-driven mobility of symbionts in a dinoflagellate-acoel worm symbiosis, revealing previously unknown mechanisms of host-mediated movement.

This study uses single-cell transcriptomics to analyze reproductive life stages of Acantharia, identifying genetic evidence for a sexual cycle involving gamete-like swarmers.

The paper tracks plastid and mitochondrial integration in a polar planktonic host over months, showing sustained benefits and highlighting a new strategy in plastid symbiosis.

This study identifies two spore types in the marine parasite Amoebophrya, revealing sexual and infectious functions, with smaller spores infecting hosts and larger spores undergoing meiosis.

This study uses metabolomics to analyze the metabolic interactions between Radiolaria and their symbiotic microalgae, revealing host and symbiont contributions to the holobiont's metabolism.

The paper investigates the life cycle and morphogenetic differentiation of decoupled cells in O. huxleyi, showing they can revert to calcified form without viral pressure and exhibit distinct transcriptomic and ultrastructural features.

This study shows that dinoflagellates can acquire and utilize haptophyte-derived plastids, demonstrating that complex plastids can be transferred between hosts.

This study identifies sugar transporter remodeling in a symbiotic microalga, revealing how metabolic exchange is reprogrammed during photosymbiosis with a planktonic host.

The paper introduces a method to separate host and symbiont reads in holobiont transcriptomes, improving assembly quality and enabling functional analysis.
